- Use a separate PVC for each protocol

#

 

 

#LLC encapsulated bridging allows any LAN frame type to be transmitted, and

#also allows IP datagrams to be sent directly on the VC. The optional

#’restriction’ parameter can limit how IP datagrams are routed to the

#interface, and on what kind of LAN frames are transmitted on it.

#The valid values for the restrction parameter are:

#

 

 

#

broute_to_ether

- Transmit all routed IP datagrams as

#

 

Ethernet frames

#

 

 

#

ether_only

- Transmit all frames (routed IP datagrams and

#

 

all bridged LAN frames) as Ethernet frames

#

 

 

#

broute_to_fddi

- Transmit all routed IP datagrams as

#

 

FDDI frames

#

 

 

#

fddi_only

- Transmit all frames (routed IP datagrams and

#

 

all bridged LAN frames) as FDDI frames

#

 

 

#Note that unless a restriction or an ARP service is specified, an

#LLC-encapsulated bridging interface will only be able to route to the host at

#the other end of the ATM PVC.

#Interface ga090 service=arp0 traffic_shape=high_speed_high_quality #Interface ga0980 service=net20 traffic_shape=low_speed_high_quality

#Interface ga0a0 service=arp0 traffic_shape=high_speed_high_quality #Interface ga0a80 service=net20 traffic_shape=low_speed_high_quality

#

#PVC’s

#Lines beginning with the keyword "PVC" define

#Permanent virtual circuits.

#

#The format of a PVC definition is:

#PVC ifname VPI/VCI \

#proto=iprawvcipnllcisisllc[,bridging]vcmux_bridge,bprovc_atmp \

#[input_aal=35NONE] [traffic_shape=shape] \

#[dest_if=logical_if [dest_vc=VPI/VCI]]

#

#The first three parameters (ifname, VPI/VCI, and proto) are mandatory.

#’ifname’ specifies the GigaRouter ATM logical interface in the usual

#format (e.g., ga030, ga0e80).

#

#’VPI/VCI’ specifies the (decimal) Virtual Path Identifier and

#Virtual Circuit Identifier of the PVC, separated by a slash (/).

#’proto’ specifies the protocol to be supported on this PVC. Legal

#values are:

#

’ip’

Internet Protocol (with LLC/SNAP headers)

#

’raw’

raw adaptation layer (AAL-5 or AAL-3/4) packets

#

’isis’

IS-IS packets

#

’llc’

any LLC-encapsulated protocol supported by the GRF
